The DBH 5561 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It measures 28 mm at the shaft, 40 mm at the housing and 7.00 mm in height, and its Lz design covers a range of industrial sealing needs. MR supplies this brand and can help you confirm whether it fits your application.

This seal carries the DBH brand and the code 5561. Its dimensions are shaft 28 mm, housing 40 mm and height 7.00 mm. The Lz designation refers to a lip profile made to work on rotating shafts where lubrication is present. Oil and wear resistant elastomers form the body, and a spring holds the lip against the shaft to maintain contact.

You will find seals like this one in centrifugal pumps, electric motors, speed reducers, compressors, machine tools and transmission equipment. In each case, the 5561 keeps bearings and gears protected from dust, water and particles while holding oil or grease in place. Because a failed seal can lead to unplanned downtime and damage inside the machine, it is a part maintenance teams track closely.

During installation, check that the shaft hardness and surface finish are suitable and that the housing is clean with no burrs. Apply lubricant to the lip before fitting the seal, and set it with the lip facing the fluid it must retain. Selection depends on shaft speed, operating temperature and how the elastomer reacts to the lubricant in use. If any of these points are unclear, ask us and we will review them with you.

If you need a seal that works in place of the 5561, send a message with the code 5561 or the three dimensions of your application: shaft, housing and height. We can search for options in other brands or sizes that match your requirements. MR provides technical guidance to help you move forward.
